From Post Office to Store is 7.8 miles Henry would walk 2.2 hStep-by-step explanation:
From Post Office (P) to Library (L) is 6 miles, from Store (S) to Library (L) is 5 miles. And angle SLP is right angle (m∠SLP=90°).
So, from Pythagorean theorem:
[tex]SL^2+PL^2=SP^2\\\\5^2+6^2=SP^2\\\\SP^2=25+36=61\\\\SP=\sqrt{61}=7.810 249...\approx7.8[/tex]
If Henry walks 3.6 mph then:
[tex]3.5\qquad-\quad\quad1\,h \\7.8\qquad-\qquad x\\\\ x=\dfrac{7.8\cdot1\,h}{3.5}=\dfrac{78\,h}{35}=2,22857...\, h\approx2.2\,h[/tex]

Two cars are 180 mi apart and travel toward each other along the same road. They meet in 4 hr. One car travels 5 mph slower than the other car. What is the
average speed of each car?
Answers
Answer:
The speed of the slower car = 20 mph
The speed of the faster car = 25 mph
Step-by-step explanation:
Let the speed of the slower car be s - 5
Let the speed of the other car be s
Two cars are 180 mi apart and travel toward each other along the same road. They meet in 4 hr.
Hence, the total speed = Distance/Time
= 180 miles/4hr
= 45 miles/hr or 45mph
Therefore:
s + s - 5 = 45 mph
2s - 5 = 45 mph
2s = 45 + 5
2s = 50
s = 50/2
s = 25 mph
The speed of the other car = s = 25mph
The speed of the slower car be s - 5
s - 5
= 25 - 5 = 20mph
Therefore,
The speed of the slower car = 20 mph
The speed of the faster car = 25 mph

Answers
Answer:
8,000
Step-by-step explanation:
you have to move the decimal to the right 3 times. so you take 8 and move the decimal 3 times. which gives you 8000.
or 8,000
The solution is: 8x10^3 in standard notation is 8,000.
Here, we have,
given that,
the expression is: 8 x 10^3
now, we have to write 8 x 10^3 in standard notation.
we know that,
A standard notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules.
For example, 4.5 billion years is written as 4,500,000,000 years.
we know,
To change a number from scientific to standard notation, move the decimal point the number of places shown in the exponent of 10.
here, we have,
8 x 10^3
= 8 x 1000
so, we have to move the decimal to the right 3 times. so we take 8 and move the decimal 3 times. which gives 8000.
we get,
8 x 10^3 = 8000
Hence, The solution is: 8 x 10^3 in standard notation is 8000.

Answers
Answer:
No, I disagree
Step-by-step explanation:
2n^4
let's put n to a real number. How about 2.
(2*2)^4=256
(2*4)^4=4096
No, I disagree, it doesn't double the expression.
Disagree. When you double the value of n, you quadruple the value of the expression.
What is proportionality?In mathematics, proportionality indicates that two quantities or variables are related in a linear manner. If one quantity doubles in size, so does the other.
Now the given expression is,
2n^4
Let y = 2n^4
Since 2 is the constant and y and n are variables.
Thus we can write,
y ∝ n^4
This means when value of y increases one time, the value of n increases 4 times.
Thus,you Disagree. When you double the value of n, you quadruple the value of the expression.

A 6000-seat theater has tickets for sale at $25 and $40. How many tickets should be sold at each price for a sellout performance to generate a total revenue of $174,000?
Answers
Step-by-step explanation:
Let x be the amount of tickets sold for $25 and y be the amount of tickets sold for $40, since there are 6000 seats theatre then;
x+y = 6000 .............. 1
If x tickets cost $25 and y tickets are sold for $40 with total revenue of $174,000, then;
25x + 40y = 174,000................ 2
From 1, x = 6000-y ............ 3
Substitute equation 3 into 2:
25x + 40y = 174,000.
25(6000-y) + 40y = 174,000
150,000-25y + 40y = 174,000
150,000+15y = 174,000
15y = 174,000-150,000
15y = 24,000
y = 24,000/15
y = 1600
Substitute y = 1600 into equation 3:
x = 6000-y
x = 6000-1600
x = 4400
Hence 4400 $25 tickets and 1600 $40 tickets must be sold to generate a revenue of $174,000

() = + + .
, ( ≤ ≤ )
(a)ABX Clothing sells the jackets at $90 each. Find the revenue function.
(b) Find the profit function.
(c) How many should ABX Clothing manufacture to make a profit? (Round your answer up to
the nearest whole number.)
Answers
Answer:
a. R(x) = 90x b. -1500 -10x - 0.2x c. 148
Step-by-step explanation:
a. Since we have x jackets produced at a rate of $90 per jacket, the revenue function, R(x) = rate × number of jackets = 90 × x = 90x
R(x) = 90x
b. Since the cost function is C(x) = 1500 + 100x + 0.2x, the profit function P(x) = Revenue function - cost function = R(x) - C(x) = 90x - (1500 + 100x + 0.2x)
P(x) = -1500 + 90x - 100x - 0.2x
P(x) = -1500 - 10x - 0.2x
c. For a profit, P(x) > 0
-1500 - 10x - 0.2x > 0
0.2x + 10x + 1500 < 0
10.2x + 1500 < 0
10.2x < -1500
x < -1500/10.2
x < -147.05
x < -147
So, ABX Clothing needs to produce greater than 147 jackets to make a profit. So, they need to make 148 jackets to make a profit.

What is the equation of the line that passes through the point (4,0) and has a slope of 5/4
Answers
Answer:
The answer is y=5/4x-5
Step-by-step explanation:
The required equation of the line that goes through the point (4, 0) and has a slope of 5/4 is y = 5/4x - 5.
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
The equation of a line with slope m and passing through the point (x₁, y₁) can be found using the point-slope formula:
y - y₁ = m (x - x₁)
Plugging in m = 5/4, x₁ = 4, and y₁ = 0, we get:
y - (0) = 5/4 (x - (4))
Simplifying, we get:
y = 5/4x - 5
Thus, the equation of the line is y = 5/4x - 5

24. Critical Thinking Anika wants to determine the maximum
number of tulip bulbs (t) she can purchase if each bulb costs $1.50.
She will also need to purchase separate pots for each bulb at $1.25
each and a bag of potting soil for $10.00. Set up an inequality to
determine how many tulip bulbs Anika can purchase without
spending more than $20.00, and solve it. Can Anika buy exactly
enough bulbs and pots to spend the full $20.00? Explain. Can you
think of a better inequality to describe the answer?
Answers
Answer:
t ≤ 3 ; kindly check explanation for more explanation
Step-by-step explanation:
Given that :
Number of tulip (t) =?
Cost of bulb = $1.50
Pot for each bulb purchased at =$1.25
Bag of potting soil = $10.00
Number of tulip bulb that can be purchased without spending more than $20
Cost of tulip bulb = [(cost per bulb + cost per pot) * number purchased (t) + cost of bag of potting soil]
Cost = [(1.50 + 1.25)t + 10]
If spending should not exceed $20
2.75t + 10 ≤ 20
2.75t ≤ 20 - 10
2.75t ≤ 10
t ≤ 10/2.75
t ≤ 3.64
He cannot purchase more than 3 tulip bulbs
Anika cannot buy exactly enough tulip bulbs an pot to spend the full $20 because the number obtained is a fraction and not a whole number.
Let V be the volume of the pyramid of height 11 whose base is a square of side length 6. Find a formula for the area A of the horizontal cross section at a height y.
Answers
Answer:
Base area = 36
Volume of the pyramid = 132
Step-by-step explanation:
Volume of a pyramid = Base Area × Height/3
Base area = Length × Length (since base of the pyramid is a square)
Given the side length of the square = 6
Base area = 6×6
Base area = 36
Given height of pyramid =11
Volume of the pyramid = 36×11/3
Volume of the pyramid = 12×11
Volume of the pyramid = 132
